Advent of Code 2022

Here are my solution for Advent of Code 2022 - in Rust!

Usage

cargo run <DAY> <PART>

where we want to solve PART (a for first part, b for second) of the problem of the DAY.

Example:

cargo run 1 a

This "program" allow to run code to solve a part of a given day and includes:

• Reading input from file in input folder (expected name is {DAY}.txt)
• Calling the respective method for a given day and part. Solutions should be placed in days folder with day{DAY:0>2}.rs name. The method to solve the first part should be called solve_a for the first part and solve_b for the second. The method should receive one argument with the input as a String and return a Result with a String indication the problem solution (if the problem was solved) or with an error string to be output explaining what error happened.
• Outputing the solution and the time taken by the solving method (if it returned an Ok result)

Performance

Time taken to complete each part of each day. Very unreliable times calculated by averaging 10 runs of each part, which were run on my PC while I was listening to music and had N Firefox tabs open :)

Day	First Part	Second Part
